Original application medians-13, 1925, Serial No. 36,982. Divided and this application filed November 30,

1926. Serial No. 151,897. i

This invention relates to'themanufacture of tuft or pile fabrics, such as Axminster carpets and the like, and aims particularly to provide an improved tuft yarn carrier or tube frame, and receivers or tubes therefor, the invention in certain respects constituting animprovement upon the device of the atent to Perry, No. 1,520,595, dated Decem er 23,1924. The present application is a divisional of my co-pending application Serial No. 36,982, filed J une 123, 1925.

In the drawings illustrating by way of example oneembodiment of my invention:

i Fig. 1, is a plan View of one end of a yarn carrier or tube frame in accordancewith my invention;

Figs, 2, 3 and {L are respectively a plan View, and opposite side elevations of one of the yarn receivers or tubes. 1

Referringfirst more particularly to Figs. 2 to 4, the individual yarn receivers or tubes embod ing one form of my invention are each in icated as a whole at 1. They are of the wallor slot-threading or openwall type, each being formed from a suitable sheet or blank, preferablyof sheet metal, which is folded into a general tubular form.

As best seen in Fig. 2, the opposite side edges of the blank are so formed and arranged as to provide an undulatory slot 2 extending the length of the enclosed portion of the tube in, a wall or walls thereof. Said slot leads from the trough or mouth 3 of the tube, extending first transversely and herein diagonally across the upper wall 4 from a point adjacent one side wall 5, and

then down and along the opposite side wall 6. Said last mentioned side wall 6 desirably projects longitudinally somewhat beyond the other side wall 5, as indicated at 7,--see particularly Fig. 4-and merges into a lip or guide 8 extending toward the opposite side of the tube and in substantially the same plane with the top wall 4 of the latter.

Said guide 8 will engage a yarn which is drawn lengthwise along and above the tube and, cooperating with the adjacent inclined edge 9 at the mouth of the slot, will positivel compel the yarn to enter the slot instea of slipping off to either side of the tube, as may frequently happen with a tube such as that of the Perry patent wherein the slot mouth is in a side wall. The yarn therefore maybe drawn directly in alignment with the tube, and no transverse move ment of or pull upon the yarn is required to cause it to enter the slot, as would be necessary in the absence of some such guiding or retaining means the lip 8 herein. Said lip, which preferably extends upwardly at least'to the level of the top wall of the tube andis desirably inturned, also assists in retaining the yarn in the tube when threaded. As shown in Fig. l, the receiversor tubes 1, are employed in connectionwith a yarn carrier or tube frame which comprises a series of said receivers or tubes. arranged in parallelism or substantially so, and. attached to a suitable carrierbar 10 having at each end a bearing support 11 for the adjacent pintles of the yarn spool or'spools, the yarn carrier or tube frame being constructed to receive one or-more spools, as desired.

My present invention is not limited to the particular embodiment herein shown and described, its scope being set forth in-the following claims 1. A receiver or tube for tufting yarns in carpet manufacture comprising a metallic member of tubular formation having an undulatory longitudinal slot through which the yarn may be threaded into the bore of the tube, said slot having amouth at the top wall of the tube adjacent one side wall, from which mouth said slot leads forwardly and transversely across the top wall of the tube, the tube side wall opposite to that above mentioned having a lip for guiding a yarn into the mouth of the slot and retaining it therein.

2. A receiver or tube for tufting yarns in carpet manufacture comprising a metallic member of tubular formation having an undulatory longitudinal slot, said slot leading from the yarn receiving end or mouth of the tube adjacent one side thereof, extending across its top wall, and thence down and along its opposite side wall in a curving path to the outer or free end of the tube.

3. A tube for tufting yarns in carpet manufacture comprising a metallic tubular member having a longitudinal slot in a side wall thereof, said slot at its thread-receiving end extending up to the top wall of the tube, and

a. lip supported on the side wall containing the slot and efl'ective to prevent a thread drawn along the tube from slipping ofi to the side thereof without entering the slot.

4. A tube for tufting yarns in carpet manufacture comprising a metallic tubular memher having a longitudinal slot in a side wall thereof, said wall at the, mouth or threadreceiving end of the slot being extended upwardly at least to the level of the top wall of the tube.

5. A tube for tufting yarns in carpet manufacture comprising a metallic tubular mem her having a slot extending from end to end of its enclosed portion, a portion of said slot being in a side wall of the tube and the mouth or thread-receiving end being in the top wall.

6. A receiver or tube for tufting yarns in carpet manufacture comprising a metallic member of tubular formation having an undulatory longitudinal slot through which the yarn may be passed into the tube, said slot having a mouth in the top wall of the tube adjacent one of its side walls, from which month said slot leads forwardly and transversely across thetop wall of the tube, the tube side wall opposite to that above mentioned having a lip approaching said first mentioned side wall and forming a yarn guiding and retaining member adjacent the mouth of the slot, the outer edge of said lip being laterally inclined to conduct the yarn to said mouth whereby a yarn drawn along and above the tube in parallelism with its longitudinal axis will be caused to enter the slot with certainty, avoiding the necessity for relative transverse movement between the tube and the yarn to cause such entrance.

7. A tube frame for the control of tuft yarns for weaving, said frame comprising a carrier bar, and a series of transversely extending tubes along said bar, said tubes each having a yarn laying slot from end to end in a wall or walls thereof, and means at the mouth or yarn receiving end of said slot for causing a yarn drawn axially alon the tube positively to be conducted into am retained in said slot.

8. A receiver or tube for tufting arns in carpet manufacture comprising a tu ular member having a yarn laying slot from end to end in a wall or walls thereof, and means at the mouth or yarn receiving end of said slot for causing a yarn drawn axially along the tube positively to be conducted into and retained in said slot.

in testimony whereof, I have signed my name to this specification.
